Products

Overview

The LCX257 is a quad 2-input multiplexer with 3-STATE outputs. Four bits of data from two sources can be selected using a Common Data Select input. The four outputs present the selected data in true (non inverted) form. The outputs may be switched to a high impedance state by placing a logic HIGH on the common Output Enable (OE#) input, allowing the outputs to interface directly with bus-oriented systems. The 74LCX257 is fabricated with advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.

  • This product is general usage and suitable for many different applications.

  • 5V tolerant inputs and outputs
  • 2.3V-3.6V VCC specifications provided
  • 6.0 ns tPD max (VCC = 3.3V, In → Zn), 10 µA ICC max
  • Power down high impedance inputs and outputs
  • Supports live insertion/withdrawal (Note 1)
  • Implements patented noise/EMI reduction circuitry
  • Latch-up performance exceeds 500 mA
  • ESD performance: Human body model > 2000V Machine model > 200V

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
